XBRL — eXtensible Business Reporting Language

XBRL (eXtensible Business Reporting Language) is an XML-based computer software language that is developed specifically for the automation of business information requirements, such as the preparation, sharing and analysis of financial reports, statements, and audit schedules. XBRL labels companies' financial and other data with codes from standard lists (taxonomies) so that investors and analysts can more easily locate and analyse desired information. XBRL makes the analysis and exchange of corporate financial information easier and more reliable by allowing data to be extracted and processed automatically by XBRL-aware applications.

XBRL is a royalty-free, open specification for software being developed by a non-profit consortium consisting of over 170 leading companies, associations, and government agencies around the world. Anyone interested in applying XBRL to business reporting processes can receive a license from XBRL International. See the XBRL International Organisation Website.

Specifically, XBRL defines data-formatting conventions and vocabularies for marking up and describing business report data, such as sales or net assets. Like XML, it is tag based. Descriptions in the form of tags or labels are attached to the various pieces of business data. These tags describe the particular piece of data in terms of an agreed-upon vocabulary. That vocabulary is referred to as an XBRL taxonomy, the specific system of tags.

Once an organisation has the appropriate taxonomy, it can enable its reports for XBRL. From there, organisations can more easily use and share data from the reports within the organization and between organizations. XBRL-aware applications can take advantage of the high level of specificity and self-describing nature of the tags to automatically process the information for purposes of reporting and analysis. XBRL is independent of any hardware platform, software operating system, programming language or accounting standard.

XBRL International

XBRL International is a not-for-profit consortium of approximately 550 companies and agencies worldwide working together to build the XBRL language and promote and support its adoption. The consortium members meet periodically in international conferences, conduct committee work regularly via conference calls, and communicate in email and phone calls throughout the week.

IFRS XBRL Taxonomy

The IASC Foundation (IASCF) has developed a high quality XBRL 'taxonomy' for IFRSs (in effect, a dictionary of data tags that explains what each tagged element is and how it should be treated under IFRSs) that will be maintained in line with the annual Bound Volume of IFRSs.

In November 2002, the XBRL International Steering Committee (ISC) issued the IAS Primary Financial

Statements (PFS) Taxonomy as an XBRL Recommendation and also issued the IAS Explanatory Disclosures and Accounting Policies (EDAP) Taxonomy as a Public Working Draft. Both the PFS and EDAP taxonomies are available on the Internet from XBRL International's XBRL Resource Center.

The PFS Taxonomy includes XBRL representations of a classified balance sheet, an income statement, a statement of changes in equity, and a cash flow statement. The PFS Taxonomy encompasses the core financial statements that private sector and certain public sector entities typically report in annual, semi-annual, or quarterly financial disclosures as required by IAS 1.7 and IAS 34.8.

Significant accounting policies and other explanatory notes are modelled in a separate XBRL taxonomy, the Explanatory Disclosures and Accounting Policies (EDAP) taxonomy, which has been released as a public working draft.

IASC Foundation XBRL Activities

The IASB has created a Separate Section of its Website – www.iasb.org/xbrl that focuses on matters relating to XBRL. On that site you will find IFRS-related XBRL news, links to various taxomonies, extensions, translations, educational materials, and upcoming events, among other information.

Fundamentals of XBRL

On the IASB XBRL web page is an excellent overview of the Fundamentals of XBRL.

September 2004: SEC proposes voluntary XBRL filings

As part of its initiative to assess the benefits of tagged data and its potential for improving the timeliness, accuracy, and analysis of financial disclosures by public companies, the US Securities and Exchange Commission has proposed to establish a voluntary program allowing registrants to file supplemental financial information using eXtensible Business Reporting Language. The program would begin with the 2004 calendar year-end reporting season. In addition to domestic issuers, the voluntary program is available to foreign private issuers that otherwise file financial information prepared in accordance with US GAAP. The Commission also issued a concept release on the benefits and implications of tagging data for filers, investors, the Commission, and other market participants, and on the suitability of the XBRL format.

July 2007: IASCF seeks members for two XBRL committees

The Trustees of the IASC Foundation have invited applications for membership of two committees relating to the Foundation's work on XBRL – an XBRL Advisory Council (XAC) and an XBRL Quality Review Team (XQRT):

  • The XAC will provide strategic advice to the Trustees and the Foundation's London-based XBRL team on the future development and adoption of the XBRL Taxonomy for International Financial Reporting Standards (IFRSs). It will comprise ten members who should broadly reflect the diverse areas and professional interests affected by XBRL adoption and the implementation of IFRS taxonomies.
  • The XQRT will review the developed taxonomies and offer strategic advice and practical recommendations on the quality of the IFRS taxonomy.

Discussion at the October 2007 IASB Meeting

The Board participated in a session on the eXtensible Business Reporting Language (XBRL) project led by staff of the XBRL team of the IASC Foundation. The session was designed to refresh Board members' knowledge of the XBRL project and to bring them up to date on developments within the IFRS-related aspects of the project.

In particular, the IASCF staff noted that its XBRL project team has expanded and now includes technical, accounting, and translation specialists. The XBRL team has put in place procedures that should enable it to ensure that revised IFRS XBRL taxonomies are released at the same time as the annual Bound Volume.

Although the session was informational, several Board members expressed the hope that there could be even more cooperation between the XBRL project team and the IASB staff such that potential problems or inconsistencies in IASB standards could be identified through the XBRL tagging/taxonomy process, before the standard is issued.

November 2007: Appointment of XBRL Advisory council and XBRL Quality Review Team

December 2007: Heads Up on US GAAP XBRL taxonomy

On 5 December 2007, the US Securities and Exchange Commission released the XBRL US GAAP taxonomy for public comment. The taxonomy is a collection of computer 'tags' that can be applied to financial data included in SEC filings to make the data interactive and more useful to investors. The public comment period concludes 4 April 2008. Some time in 2008, the SEC is likely to propose a rule that would require certain registrants to incorporate interactive data into future SEC filings. We have posted the 10 December 2007 edition of the Heads Up Newsletter (PDF 111k) from Deloitte & Touche LLP (United States), which describes the US GAAP XBRL taxonomy.

May 2008: All SEC registrants (US GAAP or IFRSs) would file XBRL data

The US Securities and Exchange Commission has proposed to require all public companies in the United States to file their data with the SEC in XBRL format. XBRL reporting would be required for registrants using either US GAAP or IFRSs as published by the IASB. The transition would take three years:

  • Companies with worldwide public float over $5 billion (approximately the 500 largest SEC registrants) using US GAAP would be required to make financial disclosures using XBRL for fiscal periods ending in late 2008. That data would become available in early 2009.
  • The remaining companies using US GAAP would provide XBRL data over the following two years (mid-cap accelerated filers in in 2009 and small-cap in 2010).
  • Companies using IFRSs would provide the disclosure for fiscal periods ending in late 2010.
The XBRL disclosure would be provided as additional exhibits to annual and quarterly reports and registration statements. Companies also would be required to post this information on their websites. Click for SEC Press Release (PDF 49k).

The questions are below. Download Deloitte's new booklet Why You Need to Know About XBRL (PDF 153k) for answers. The booklet is written from the point of view of a US SEC registrant, but most of the answers are relevant in a global context as well.

Why you need to know about XBRL
  1. What is XBRL or 'interactive data'?
  2. How does XBRL make data interactive?

  8. Under the proposed rules, when must the interactive data (XBRL-based information) be submitted to the SEC?
  9. Will XBRL replace the EDGAR (Electronic Data Gathering, Analysis, and Retrieval) system? Will current filing formats in the EDGAR system be replaced by XBRL (i.e., will registrants be required to file XBRL documents rather than conventional financial statements, or will they be required to file both)?
  10. What steps can a registrant take now to prepare for the SEC's XBRL mandate?
  11. What implementation options are available to a registrant for preparing XBRL-based financial statements?
  12. Will XBRL documents submitted to the SEC be subject to an audit requirement? What might assurance on XBRL-formatted financial statements include?
  13. Do the current proposed rules apply to mutual funds?
  14. Where can I find more information about XBRL?
  15. How can Deloitte help companies prepare for and make the most of XBRL?
